Harassment and ignoring of emails!!!!!! MBD debt collection

This place harasses people!!!

My number is linked to someone else's account. I have informed them about this, I have told the people at MBD debt collection as well, I have given them this accounts correct contact information, I have gone to the store and they put a complaint in, I have emailed(WHICH THEY NEVER EVEN RESPONDED TO!) , yet I STILL get harassed!!!! It has gotten to the point where when I answer the phone they put it down. They are just calling me to harass me!!! I am sick of this. I need this CORRECTED AS A MATTER PF URGENCY!!!
